Steadfast perpendicular exchange coupling in an ultrathin CoO/PtFe double-layer: strain and spin orientation
A. D. Lamirand, M. M. Soares, A. Y. Ramos +5
We report on the exchange coupling and magnetic properties of a strained ultrathin CoO/PtFe double-layer with perpendicular magnetic anisotropy. The cobalt oxide growth by reactive…

Emergence of ferromagnetism and Jahn-Teller distortion in low Cr-substituted LaMnO3
A. Y. Ramos, H. C. N. Tolentino, O. Bunau +9
The emergence of a ferromagnetic component in with low Cr-for-Mn substitution has been studied by x-ray absorption spectroscopy and x-ray magnetic circular dichroism at…

Stability of the Ni sites across the pressure-induced metallization in YNiO3
A. Y. Ramos, C. Piamonteze, H. C. N. Tolentino +7
The local environment of nickel atoms in Y NiO3 across the pressure- induced insulator to metal (IM) transition was studied using X-ray absorption spectroscopy (XAS) supported by a…
